Well, me too, sorta. Not *very* modest machines. But certainly anything
>300mhz (and I suspect somewhat slower). I do have "slow downs" on
occasion but havn't pinned anything down (e.g., it could be background
processing, it could be perceptual acceleration :)).

I know some people report that using VNC rather than X to display over a
network can be substantially faster (given that VNC is designed to be a
pixel shipping protocal that's not surprising). I have no idea if this is
useful info for this case :)
